In theOther sustainable aspects of the design include the
vegetation on the exposed roof sections of the ground
floor podium. Occupying approximately 2 percent of
the total surface area of the building, the vegetation
helps to prevent the surrounding drains from becoming
overloaded during storms, according to the United
Nations’ Denmark operations website. Moreover, a system
of sand traps and oil separators has been designed
to filter storm water that collects on the pavement before
it is returned to the harbor, thus reducing both the
risk of pollution and the site’s reliance on the municipal
sewage system.
